Anyone noticed this about WB?

I put a Widgetbucks widget back on my site and beyond the fact that the holidays seem to be playing havoc on their statistics, I am wondering about something.

I only seem to get about a third of the impressions that Analytics tells me, even though the widget is embedded in such a way that it is displayed on every page.

Is this normal for you all too? While I understand that only the US and Canada traffic is counted in the non-international impressions, there is still a wide margin between what Analytics says and what WB says. What other factors are there?

It could be because that the ads in wb will not be displayed at all most of the time when it is loading only blank space will be appearing. They need to tweak it a bit more to make it perfect.

WB is terrible. Too long to load. Insufficient selection of ads. Random changes in your earnings. I'll go with Google any day.
